摘要： In an image heating apparatus, outer peripheral surfaces of two endless belts are held in contact with each other to form a nip portion, and a recording material bearing a toner image is heated at the nip portion while being pinched and conveyed. In the image heating apparatus, the nip portion has a pre-nip portion formed by regions of the endless belts with no backup by pressure members, and a pressure nip portion where one endless belt with backup by the pressure members is held in contact with another endless belt. The image heating apparatus is capable of securing a large nip width compatible with an increase in speed and free from “pressure-absence” leading to image abnormality such as misregistration, thus enabling an image having a sufficient gloss to be obtained.

摘要： In an image processing apparatus according to the present invention, the density of each pixel in a multi-level pixel block composed of a set of input multi-level pixel data is examined and a decision is made as to whether a pixel having a density which does not reach the minimum density below which printing is impossible, is present in the multi-level pixel block. If a pixel having a density below the minimum density is detected, the density of this pixel is distributed to another pixel position in the multi-level pixel block. In this manner, the number of pixels with a density which does not reach the minimum density below which printing is impossible, is reduced within each multi-level pixel block.
